The invention relates to rotary duplicators, for instance rotary stencil duplicators and rotary type setting duplicators, and to the collecting trays used with such machines, that is to say the trays which are adapted to receive sheets of paper after they have been passed through such machines.

The invention has been devised with the object of producing a collecting tray for said 110 machines which can be adjusted to any size of paper to be used in a machine and when not required to be used can be collapsed so that it will occupy but a small space, and when so collapsed and turned upwards will be clear of all parts of a machine and can be housed in the cover of the machine.

The invention is illustrated by the accompanying drawings.

Figs. 1 and 2 of the drawings are respec- 2o tively a side view and a plan of a collecting tray for rotary duplicators constructed in accordance with the invention, the tray being shown connected at its inner end to the base plate of a machine. Figs. 3 and 4 are fractional views illustrating a modified detail of construction.

Referring now to these drawings, a collecting tray for a rotary duplicator, according to the present invention, is constructed of end members 1 and 2, a contractible and extensible bottom 3, and members 4 on said bottom which serve as the sides of the tray. The outer end member 1 of the tray may consist of a stamping which is made of a shape similar to one end of the tray or drawer of a match or like box, that is to say comprises a bottom 1 of narrow width and walls 1" disposed at right angles to one another and to said bottom, while the other or inner mem- 4 her 2 of the tray may consist of a rod which is adapted to be mounted at its ends in bearings, for instance, eyes 5, secured to the base plate 6 of the machine with which the tray is used, axial movement of said rod in said bearings or eyes being prevented by making the outer parts of the rod of reduced diameter or by providing the rod with suitably positioned collars. The extensible and contractible bottom 3 of the tray may be of sim- 5 ilar construction to lazy-tongs, that is to say,

may, as shown, consist of a number of levers 3 crossing-one another and pivotally connected to one another at their centres and ends. This extensible and contractible bottom 3 is connected to the outer end member 1 of the tray by means of pins 7 and 8 passing through the free ends of the levers 3' at the front end of the lazy-tongs, one of these pins, the pin 7, engaging with a hole 9 formed in the bottom 1 of the end member and the other pin 8 passing through and travelling in a slot 10 provided in the bottom of the end member. The other end of the extensible and contractible bottom 3 of the tray is connected to the rod constituting the inner end member of the tray through the medium of sleeves 11 which are slidably mounted on said rod and are provided with extensions 11 to which are pivoted the free ends of the levers 3' at this end of the extensible and contractible bottom 3 of the tray. The hereinbefore mentioned members at which serve as the sides of the improved tray may consist, as shown in Figs. 1 and 2, of upwardly bent extensions of the levers at the centre of the lazy-tongs or bottom of the tray, or may consist, as shown in Figs. 3 and 4, of posts 4: supported by said levers, in which case the lower ends of the posts may be reduced and serve as pivot pinsfor the outer ends. of the levers. The number and length of the levers 3' of the lazy tongs or extensible and contractible bottom 3 oi the improved tray are such that when the tray is fully extended it will be adapted to receive sheets of paper of the largest size which will be used with the machine. The eyes or bearings 5 in which is mounted the rod or inner member 2 of the improved tray are secured in such positions on the base plate of a machine that it will be impossible for the tray when contracted and turned upwards to come in contact with any part of the machine which might be damaged by such contact. The tray is provided at its front with means, such, for instance, as a foot 12 secured to the centre of the outer member 1 of the tray, by which the tray will be supported in a horizontal position when in use.

What I have invented and desire to secure by Letters Patent of the United States is as follows 1. A collecting tray or a rotary duplicator comprising an extensible and contractible bottom, an outer end member connected to the front of said bottom and an inner end member connected to the rear of said tray and pivotally mounted on or adapted to be pivotally mounted on the base of the machine, and members on said bottom which serve as the sides of the tray, substantially as described.

2. A collecting tray for a rotary duplicator consisting of an outer end member comprising a bottom of narrow width and side walls and an end wall disposed at right angles to one another and to said bottom, an inner end member pivotally mounted on or adapted to be pivotally mounted on the base plate of the machine, an extensible and con-tractible bottom of similar construction to lazy-tongs connected to said end members, and vertically disposed members on said levers serving as the sides of the tray, substantially as .described.

3. A collecting tray for a rotary duplicator consisting of an outer end member comprising a bottom of narrow width and side walls and an end wall disposed at right angles to one another and to said bottom, an inner end member consisting of a rod pivotally mounted on or adapted to be pivotally mounted on the base plate of the machine, an extensible and 'contractible bottom of similar construction to lazy-tongs operatively connected at its rear to the inner end member of the tray by means of sleeves slidably mounted on said rod and operatively connected at its other end to the outer end member of the tray by means of pins passing through the free ends of the levers at the front end of the lazytongs and engaging with a hole and a slot in the bottom of the front member of the tray, and ver-ticallydisposed members on said 1eyers serving as the sides of the tray, substantially as described. 7
